Default Schematics & standards

... wire-connecting/jumping convention: here I much prefer the
modern approach, which is to use a dot for a connection and no dot for
no connection, rather than the clumsy "loop" to indicate one wire
jumping over another with no connection.


I find the 'gap' convention is easy to draw (with a computer) and
extremely easy to read. It also looks tidy. Four-way junctions which
could be mistaken for crossings should never be used, they should be
staggered instead.

e.g.

BZZZZZZT! Fail.

While the gap thing looks OK for non-crossing wires, I have to ding the
drafts-person of that schematic for the following:

o Idiosyncratic symbols for electrolytic cazapitors[1]
o Idiosyncratic ground symbol (one horizontal line????)
o And no, I disagree about those offsets for connecting wires.

That's totally unnecessary he it would be quite obvious that all
those vertical wires connect to what is obviously a bus or rail. A
well-drawn dot is all that's needed there.

(And I don't much like their transistor symbols either)
